Tehran will not negotiate the renewal of the 2015 nuclear deal indefinitely, Iranian Foreign Ministry spokesman Saeed Khatibzadeh on his Twitter.

Khatibzadeh noted Iran's active cooperation in negotiations to revive the Joint Comprehensive Action Plan, despite obstacles from the United States, Tasmin reported.

According to the spokesman, with an unwavering commitment to salvaging a deal that the US was trying to torpedo, Iran was the most active party in Vienna, proposing most of the projects.
